A few days ago I started getting "undo typing" notifications every few seconds when typing and "undo delete" notifications when deleting emails, even though I wasn't shaking the phone at all. I disabled this and thought nothing more of it.

A day later I open Safari and it immediately turns 90 degrees anticlockwise into landscape mode and stays there. So does every app that will open in landscape. Nothing I do will make the screen rotate into any other position so I have to lock rotation to keep the phone in portrait mode. I also find that the compass doesn't work (can't calibrate it) and any app that uses augmented reality (FlightRadar 24, Sky Safari etc) won't work either when I point the phone up at the sky.

In addition, the phone is going through the battery at the rate of 10%, per hour on standby and if I dare to use it it gets quite warm and uses 20% an hour or more.

The phone is 2 weeks out of warranty and I'm not in a position to take it to a Genius Bar until January as I'm working abroad.

I reckon I have a dead sensor, at the very least. Any other suggestions, please?

I've restarted and done a soft reset, with no effect. I can't really do a factory reset at the moment as I'm abroad, only have access to a very slow Internet connection (500kb/s shared between 15 people!) so downloading my apps again isn't an option and can't easily back up the phone. I'll certainly do that once I get home. To me it has all the symptoms of a hardware fault. Unless Apple opens a store in Libya (seems unlikely!) I'll just have to wait until January.

Well you might want to talk to Apple and take notes, so that you can just get in touch with them in the future when you can. Letting them know that this problem occurred before the warranty expired

Thought I'd update this thread because of the good customer service I received from Apple. As I mentioned above, I was working abroad until last week and only managed to get the phone to a Genius bar yesterday. I had already discussed the problem with Apple by phone and had been told I would have to pay something over £250 for repair. At the Genius bar I was very surprised to be told that they would honour the warranty and I was given a replacement handset within 10 minutes of walking into the store.
